Global energy consumption is rising and the relative contribution of lighting in
buildings to that total is also increasing. In an academic institution, the dominant form
of lighting is fluorescent, but this will soon be surpassed in terms of performance by
LED lighting, which are already starting to be more widely used. This thesis examines
feasibility study on LED lighting as a retrofitting solution to conventional fluorescent
lighting systems, with an in-depth audit on lighting system in UNIKL MICET and
assesses their potential to provide an equivalent lighting environment with various
lighting energy saving strategies. Hence examines Return of Investment (ROI) when
retrofitted with LED lighting.
Methodology on assessment of lighting system were carried out both manually and
with computer based simulation software (RELUX). Manual assessment of lighting
were carried out in accordance to Bureau of Energy Efficiency Code (BEE Code) for
Installed lighting Efficacy Ratio (ILER). The results on assessment shows reviewing of
lighting system is needed.
A visual performance study was also conducted, to ascertain if there is a difference in
task based performance on paper and simulation screens between fluorescent lighting
and LED lighting, in a classroom environment. Subjective opinions on preference
between the two light sources was also investigated. Computer simulation results
showed lighting levels and distribution in case study room could be replicated with
good agreement, offering a lighting load demand reduction and reasonable ROI
